This invention 'relates :to looking niecbzb` nisms 'for 'safes and morejprtlcularly to looking lne'lhanis'm yfor double doors'aes or vaults .for tabernacles'orother uses.

nother object i's to provide a Safe door locking mehnnisin which may be operated by pan o'rdinry tuinblerrelease or other'ltey for operating the looking l bolts and for swinging the .doors Without the lproyison of handle's, knobs, or the like, commonly zused for thepurpo'se. Y

ments of the bolts.l Preferably, the doors are arranged to be simultaneously opened through mechanism indicated at 36 and particularly described and claimed in my Patent No. 1,577,836, dated March 16, 1926, and It will be apparent and understood that any lock mechanism whatsoever that may be operated through the medium of a single key is intended to be incorporated in the pinion 27 as such mechanisms are well known inthe art. vAs each of the teeth. of the pinion 27 constitutes a projection rigidly secured to the key operable member and as adjacent teeth on the rack 26 provide opposed shoulders between which one tooth of the pinion 27 engages, I may refer to this mechanism in just such manner in the claims. y

From vthe foregoingy description, taken in connection with the drawing,'it is believed that the construction and operation of the locking mechanism will be clearly under- A stood. It Will also be appreciated that, since v member, including many variations and modiiications may be made of this structure within the spiritrof my invention and the scope vof the appended claims, I do not desire to be limited to the details of construction and operation shown anddescribed.

I claim: i f

1. AV double door locking mechanism for safes comprising, a key operable pinion, a a rack for engaging said pinion, carrying a plurality of horizontally slidable locking bolts, a second rack carried by one of said bolts,.a vertically slidable locking bolt having a rack associated there- With, and apinion for operatively connecting the two last said racks.` i

2. A double door locking mechanism comprisingfa horizontally movable` locking bolt, a ,vertically movable locking bolt, a key operable lock including a pinion, a rack connected to said horizontally movable bolt and operably connectedfto said pinion, and mechanism including a second pinion operably connected to said vertically movable bolt :for locking and unlocking movements thereof simultaneously with andin the order of lockingV and unlocking movements of said horizontally movablebolt. j 1

3. A double door locking mechanism comprisin a pair of horizontally movable` locklng bo ts mountedl on one doory in spacedrelation to oneano'ther and adaptedto lockingly engage the Iopposite and v'cooperative oor, means rigidlyconnecting said bolts for their simultaneous operation, a vertically movable locking bolt mounted said door and adapted to lockin'gly engage a door frame member, a key operable lock `moi1nted in the `first said door for rotation between limits, tween said lock an operative connection. be-

and said means connecting vprising,

on the first..

said horizontally movable bolts for projecting and retracting the. same into and from engagement with the opposite door when said lock is rotated in opposite directions respectively and a connection between one of said horizontally movable bolts and said vertically movable bolt for projecting and retracting the latter as and when the former is projected and retracted, respectively. ,4. A double door locking' mechanism comprising, a bolt carrying member, having a plurality of locking bolts secured. thereto in spaced relation, mounted on one door for bodily movement toward and from the opposite and cooperative door, said bolts being adapted to be received in cooperative recesses in the opposite door, a key operable member rotatably mounted in the first said door. meansv connecting said key operable member and said bolt carrying member whereby rotative movement of, said key .operable member Will bodily move said bolt carrying member to engage and disengage said bolts vinthe recesses of the said opposite and cooperative door, a bolt mounted on the first said doorfor movement at an angle to the line of movementofv the first said bolts and adapted to be received. in a recess in a door frame member, and means connecting the said last boltjand said bolt carrying member whereby the last said bolt may be projected and retracted into andout of lockingengagement with said recess in vsaid door frame member, when said bolt carrying member is bodily moved to engage and disengage the bolts it carries with and from, respectively he recesses in said opposite and cooperative oor. 5. double door locking mechanism coma pair of spaced, khorizontally movable bolts mounted on oneI door andadapted tobe received at one end of'y each in corresponding recesses formedin the opposite and cooperative door, a plate secured to, joining and bodily movable with said bolts, a vertically movablelocking bolt mounted on the rstsaid door and adapted to be received in a'recessin a door frame member, ,means connected with said bolt and plate for moving said vertically movable .bolt into and out of locking engagement in said recess in a door frame member as said'. horizontally movable bolts are movedl into and out of locking engagement with the recesses inthe 4.

horizontal ath whereby lall ofv said bolts may be loc ed and unlocked, respectively, simultaneously. l
